Hi guys –I forgot to get back to you 18 months ago after my first analysis.  You sent me a report for the Toyota WS fluid in my dad’s RAV4, which had reached the end of its useful life.  I had a shop change the filter & fluid.  The felt-like filter medium had actually started to deform, and was going to be sucked-out the top of the filter box by the pump.  With a new filter, and 8 qts of fresh fluid, I noticed an immediate improvement in shift quality.  I will definitely send you another sample in another couple years, as the vehicle doesn’t get driven much now. Keep up the good work.
